Electronic line calling and a smart court for every tennis club

In and out called before the players have turned around, plus speed, spin and full statistics for every shot. One installation on your court, one subscription, and the data stays at your venue.

3D modelling of the game

A five-shot rally the way the umpire's tablet shows it: every bounce called in or out, with speed and spin for every shot.

About us

Accuracy you can measure

Instant call. Sound and light before the players have turned around, no line judges needed.
Verified, not estimated. Every installation is checked on court with a ball machine before handover.
By the rules. If any part of the ball mark touches the line, it is in. Line width, skid and spin are all in the model.

Simple pricing

One-time installation price. Cameras, server and umpire console installed and calibrated on your court.
One subscription. Software updates, support and the match platform, month by month.
Your data stays yours. Everything is stored at the venue and keeps working when the internet does not.

Built for clubs and academies

One court, three jobs. Official calls for matches, coaching data for training, progress profiles for the junior academy.
Every shot recorded. Speed, spin, depth, net clearance, shot maps and video of every rally.
Umpire console on a tablet. Score by the rules of tennis, set and break timers, challenge replays.

The court watches every ball, decides where it landed and announces the call before the players have turned around.

Cameras around the court, one server at the venue and a tablet for the umpire. Nothing leaves the building, and nothing stops when the connection drops.

In or out, settled

Cameras watch every line from the side, never along it. The bounce is reconstructed, the mark is compared with the edge of the line, and the call goes out by sound and light before the point is over.

Speed, spin, statistics

The ball is tracked in 3D: serve and groundstroke speed, spin, net clearance, depth and bounce height for every single shot, with shot maps and a video clip of every rally.

Umpire console and academy

Scoring by the rules of tennis, timers and challenge replays on a tablet. Player profiles, drills and progress over months, so parents see how a child improves in numbers rather than in words.
